What i did once is to go to Photoshop and created an image 12 inch long and one inch wide (if you need that). Could be 1x1 centimeter as well for the Europeans. Both with lets say 300 DPI - the standard resolution for print issues. Then under image size i checked how many pixels there are now on this inch or centimeter. Ok, if i want now a 5x5" image i can multiply the amount of pixels per inch i know now by 5 and get the pixels i need to render. Wether Vue says 72 dpi or 300 does not matter, i can change that in Photoshop easily to the value i need. And i have to go to Photoshop normally anyway to change the color mode for print issues. CMYK instead of RGB.
